L4/Q ATT RNEY port thereon a sheet or board of building material M, PIG.2, such as a plasterboard ceiling sheet or a Vplywood panel.

When the hoist is tobe used, the head-carrying lifting standard isdropped to its lowermost position where the head frame is convenient tothe user. A ceiling board or panel, such as of plasterboard, libreboard,or plywood, is placed on the head frame in a horizontal position, thehead frame being disposed at the middle region of the lboard. The headframe is then raised by operating the Winch 31, bringing the horizontalboard close to the ceiling structure of the room. The hoist can beWheeled about to place the board in the desired position. If desired,the head frame can then be raised farther to abut the board against theceiling. While the head frame is in its elevated position, the board isfastened to the ceiling structure, whereupon the head-carrying liftingstandard `is lowered to its loading position, ready for the nextoperation.

If desired, the hoist head frame may also serve tc support a scaffoldboard or seat board, not shown, for use in painting, decorating, andother operations.

The hoist can be readily disassembled or knocked-down into the threeseparable units, 10, 17, and 48, as indicated in FIG. 5, to facilitatetransport and storage, and when in such condition can lbe compactlypacked. The base and head frame form two of these units, and theextensible ma'st structure, with the three brace bars thereof swunginwardly, forms the third uni-t. If desired, the winch crank handle 43may be detached and reversed to provide further compactness of the maststructure.

In the modified form of hoist shown in FIG. 6, the lifting cable 45 istrained or looped about a grooved pulley 53 mounted on a bracket 54welded or otherwise secured to the lower portion of the slidableliftingstandard 19, land the end portion of the cable extends upwardly from thepulley and is anchored on a bracket or ear 55 welded or otherwiseYsecured to the guide sleeve 21. This arrangement provides additionalmechanical advantage. The hoist of FIG. 6 is otherwise the-same as thatof FIG.1.

I claim:

1. A hoist for handling ceiling material and the like, comprising abase, a vertical post upstanding from said base, a tubular liftingstandard surrounding and vertically slidable on said post, a guidemember spaced above said base and extending about said lifting standardin slidable engagement with said standard, said standard being slidableup and down within said guide member, supporting means connecting saidguide member and base, a material support carried by the upper end ofsaid lifting standard, and winch means carried by said guide member atthe outer side of said member and including a hoisting cable exterior tosaid lifting standard and operatively connected to the lower end portionof said lifting standard.

2. A hoist forhandling ceiling material and the like, comprising a base,a vertical post upstanding from said base, a tubular lifting standardsurrounding and vertically slidable on said post, a guide member spacedabove said base and extending about said lifting standard in slidableengagement with said standard, said standard being slidable up and downwithin said guide member, three supporting brace bars connecting saidguide member and base and being divergent downwardly and outwardly, twoof said brace bars being disposed at opposite sides of said standard andlying substantially in a vertical plane of said standard, and the thirdbrace bar lying in a vertical plane of said standard spacedsubstantially 90 from said first-name plane, -a material support carriedby the upper end of said lifting standard, `and winch means carried bysaid guide member at the outer side thereof and at a region oppositesaid third brace bar and including a hoisting cable exterior to saidlifting standard and operatively connected to the lower end portion ofsaid lifting standard.

3. A hoist for handling ceiling material and the like, comprising a basehaving an upstanding projection, a vertical post upstanding from saidbase and having its lower end detachably interfitting with said baseprojection, a tubular lifting standard surrounding and verticallyslidable on said post, a guide member spaced above said base andextending about said lifting standard in slidable engagement with saidstandard, said standard being slidable up and down within said guidemember, inclined brace bars connecting said guide member `and base andbeing detachably secured to saidV base, a material support carried bythe upper end of said lifting standard and having a downwardly extendingprojection detachably interlitting with the upper end of said liftingstandard,

Vand winch means carried by saidv guide member at the outer side of saidmember-and including a hoisting cable exterior `to said lifting standardand operatively connected to the lower end portion of said liftingstandard, the connection of the upper ends of said brace bars to saidguide member being pivotal and permitting said brace bars to be swunginwardly close to said lifting standard when said bars are detached fromsaid base and said base I is detached from said post.

4. A hoist for handling ceiling material and the like, comprising across-shaped base having four -rigidlyA connected arms extendingradially from a junction, a vertical guide post upstanding from saidbase at said junction, a tubular lifting standard surrounding andvertically slidable on said post, a vertical guide'sleeve spaced abovesaid base and surrounding said lifting standard in slidable engagementwith said standard, said tubular standard being slidable up and downwithin said guide sleeve, said sleeve having thereon a pair ofdiametrically opposite laterally projecting brackets and an intermediatelaterally projecting bracket spaced substantially from said first namedbrackets, three inclined brace bars having their upper ends respectivelyconnected to said sleeve brackets and having their lower endsrespectively connected to three arms of said base, said brace bars beingdownwardly divergent with respect to each other, a winch mounted on theside of said sleeve opposite said intermediate bracket and including arotatabletdrum, and a hoisting cable wound on said drum and projectingdown- Wardly therefrom exterior to said lifting Vstandard andoperatively connected to the lowerend portion of said lifting standardfor elevating said standard.
